Magnetite Windows can be installed on a large scale on many different styles of windows. The same technology that jet planes use to seal their windows and keep their passengers comfortable can be used in your building without having to replace a single window. These windows attach to the inside of your window frames by magnetic force. There is no messy or time consuming construction. Best of all, Magnetite Windows are a fraction of the cost of glass windows. Because they are so energy efficient, they pay for themselves in energy savings alone.
